Grey’s life has been nothing but a struggle. A constant downward spiral, and it seems even reality has turned against him. Grey awakens to find that the world has gone quiet, the streets empty. You must find help.
Explore the grim world Grey lives in a completely new and unique world, and find clues to his shattered past.
Grey is a total conversion Half-Life 2 horror modification where the player must solve puzzles, fight to survive, and find out what is happening to the world around you. We have made a lot changes to the base Source engine and have added countless new mechanics in the mod such as the objective indicator, portable medkit, donator based extras, pickup animations, failed reloads, new picture based GUI elements and much, much more!

I love the look of this mod, it's exactly my cup of tea.
I've recently started mapping and im focusing alot on lighting, i wonder if someone could explain how you make the model appear glowing like that?
